Table 4. Incident rates of impaired glucose tolerance and impaired fasting glucose according to groups categorized by intake of soybean products among a subcohort of men with normoglycemia at baseline.
| Group 1 0 –1 time/week | Group 2 2 –3 times/week | Group 3 ≥4 times/week | |
|---|---|---|---|
| Case (incident rates/1000 person‐years) | |||
| Men with low BMI, n (<23.6 kg/m2) | 57 | 213 | 341 |
| Impaired glucose tolerance | 12 (67.4) | 53 (77.5) | 86 (78.2) |
| Impaired fasting glucose | 6 (32.6) | 34 (47.8) | 33 (28.4) |
| Men with high BMI, n (≥23.6 kg/m2) | 46 | 219 | 346 |
| Impaired glucose tolerance | 19 (159.7) | 75 (113.6) | 129 (125.4) |
| Impaired fasting glucose | 9 (63.4) | 38 (53.4) | 63 (55.3) |
BMI, body mass index.
Impaired glucose tolerance was defined as 2 h plasma glucose ≥7.8 mmol/L. Impaired fasting glucose was defined as fasting plasma glucose ≥6.1 mmol/L.
